OPTICAL ASSOCIATIVE MEMORY WITH BIPOLAR EDGE-ENHANCED LEARNING THAT USES A BINARY SPATIAL LIGHT MODULATOR AND A BATIO3 CRYSTAL

摘要

An optical associative memory with bipolar edge-enhanced feature learning that uses a ferroelectric liquid-crystal spatial light modulator and a barium titanate crystal is presented. During the learning procedure the bipolar edge-enhanced versions of the patterns are employed, which enable the associative memory to have a high discrimination capability. Experimental results and computer simulations are given. (C) 1995 Optical Society of America [References: 25]
